TIRE REMovEn.

`Application led February 8, 1926. Serial No. 86,767. f

My invention relates to a tire remover, and particularly to a device for removing tires, for example solid tires of rubber or other materials, from the rims or wheels to which they are cemented. One object of my invention is to providepower means foi rapidly` effecting such separation. `Anotl1erV object is the provision of such a device,-

wherein all or substantially all of the rubber, or other material, of the tire isstripped from the rim. Other objects will appear from time to time in the course of the specification and claims. f

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein` i Figure l is a side elevation;

Figure 2 is a plan view; and

Figure 3 is a detail. i

Like parts areindicatedl by like symbols throughout the specication and drawings.

A A are a pair of longitudinally disposed structural members, herein shown as I-beams having the vertical web A1 and the longitudinal flanges A2 A3 at top and bottom thereof. The members A A may'` be supported, and spaced apart, for example by l the transverse supports B B, herein shown as short I-beam sections.

Mounted at one end of the frame 1s the transverse shaft C rotatably mounted in the C10 are slides mounted upon the arms C* and adapted to be radially-moved in response to rotation of the worms C". They terminate in the outwardly extended rim engagging members C12. The shaft C also carries aratchet wheel GlL adapted to be controlled by a. dog C1" mounted upon the frame.

Mounted in the frame A,-intermediate its ends, isa shaft D having a gear D1 in mesh with the pinion D2 on an intermediate transmission shaft D3 which in turn is driven from the shaft D4E through the gear D? and pinion D6. The shaft Dt, 1n turn, u is driven through the gear DT in mesh with position.

the pinion DS on the motor shaft adapted to be actuated from` any suitable power urce, for example by the electric motor i `The shaft D `carries rotatably` mountedl i thereupon the drum E having at each end the outwardly j extending flanges or `rims E1 E2. E3 is a clutch member,-feathered upon the shaft D, and axially adjustable therealong for example `by means `of the rotationof the bolt E4 controlling the` holding plate E5. The clutchmember E? is provided with an extended member or flange E8 opposed to 'the corresponding member fEl `of the drum E.` `Interposed between them v 1s any suitable frictional member or washer i E7. Esi `is asecond clutch member, also featheredupon theehaft D," andprovided L with an extendedface E"` opposed `to the corresponding face E2 of the drum. E10 is any suitable interposedfrictional member or washer. El? is any suitable thrust member movable along the shaft D and E12 is arcam collar mounted about the shaftD` and prof vided for example with the wedge or `.cam `surfaces E1* in opposition to similarly formed surfaces Elvupon the fixed member E16. E17 is a lever controlling the cam or `wedge member El? and is adapted to be actuated for example by means of the foot pedal E13 to which itis connected by ythe link or rod El". E2 is a` tension spring tending to draw: the pedal upwardly and thus to hold the member E12 in withdrawn It will be readily` `understood `from the v foregoing that when thewfoot pedal E1S is i depressed its motion will be: transmitted through the link E to the lever or arm E17 of the cam collar E12, thereby producing an arcuate movement of the latter. j ate movement will, through the action of the companion cam faces EM and El?, cause the said cam collar to be shifted axially of the shaft D which axial movement will be transmitted through the thrust` member `E11 This arcuto the clutch member Es and winding drum Y E. The pressing together of these members v asfrictionclutches, as can bereadilynnderstood; 1 i i l The'drum E vcarries a lug G to whichrnay be secured any suitable flexible tension 111cm-, ber for example thechain G1. The chain shown.

I do not wish to limit myself to the particmay pass about the sheave G2 rotating about the shaft G3 at the opposite end of the frame. The opposite end of the chain may terminate in the hook G4.

I-I diagrammatically illustrates any suit able clamping member adapted to be secured to the severed end of the tire. I illustrate it herein as consisting of two members H1 adapted to be connected for example by the bolt IwIT2 and provided at their forward ends with converging portions H3, the inner surfaces of which may be formed with studs or points H4.

It will be realized that, whereas I have illustrated' a practical and operative device, nevertheless many changes in size, shape, number and disposition of parts may be made without departing from the spirit of my invention, and I wish my drawings to be taken as in a broad sense diagrammatic and illustrative rather than as limiting ine to the specific mechanisms Adescribed and In particular it will be realized that ular chuck shown or the particular driving l connections and driving means, or the particular clutch mechanism.

The use and `operation of my invention areas follows:

It is the practice to cement solid tires to the rims or wheels upon which they are carried, in contrast tov the detachable securing of pneumatic tires. Normally a solid tire is not removed from a rim or wheel until it is worn out, and the purpose of its final removal is prevailingly to salvagethe material of which it is composed. It is difficult to cut these tires from the rims, because the rims generally are provided with lupwardly or outwardly projecting `flanges, and to sever the tire from the rim leaves a relatively -thick layer of good rubber, if it is a rubber tire which is being removed.,` which is `either lost, or must be ploughed out at considerable diiliculty and expense.

I have developed a mechanism for quickly, efliciently and economically strippingsolid tires from rims which consists, stated simply, of providing a support for the tire or rim, and of providing means for applying a tension to the. severed end `of the tire, to

draw it away from the rim and to strip it from the cement by which it is secured. In employing my device I first mount the rim upon any suitable holding means, for eX- ample the adjustable centering and gripping means above described and shown. With any suitable severing means I then sever the tire, `to provide a relatively long thin lip of material. `This lip should be out long enough to receive a holdingr clamp, for eX- ample the clamp shown in Figure 3. The chain is then secured to the clamp, the outer end passing around Y the sheave G2, the motor is actuated, and the clutch thrown in.

tire which tends to strip it from the rim.

The rim is held against rotation, for en ample by the ratchet C14, and the dog C. If the tire tends to stick to the cement so strongly as to resist the tension, or as to tear, the operator may pass a sharp edged instrument across the inside of the tire and this is in practice sufficient to prevent binding or sticking, the tension being such that a slight touch of a sharp edged tool is suilicient. Then `a considerable length of the tire has been released, I may, if necessary, remove the holding clamp and loop the chain about the loose end of the tire. The tension `upon the chain draws the chain noose `thus formed tight and is sufficient to hold the chain against any substantial longitudinal movement along the `tire end. From time to time it becomes necessary to shift the rim, which can be done manually, if desired, it being turned preferably clockwise, as shown in Figure l, the dog thus overrunning the ratchet. I may also adjust the chain along the tire from time to time, as the separation progresses. Preferably, during the pulling, the point of separat-ion between tire and rim is above the center of rotation of the chuck, as shown in Figure l.

l The operator maintains constant control ofthe tension through the foot lever E which serves to thrust the clutch member EB against the drum E and thus the drum E against the clutch member E3. The drum is thereby gripped between two clutch members both of which rotate with the shaft, and I have illustrated an anti-friction member or washer between each clutch member and the drum. Any relaxation of pressure upon the foot Apedal permits the pedal to rise in response to the tension of the spring E2, and tension upon the chain immediately ceases.
